Finally, thanks to @Yves_BAZIN I now have ESP32 with no more flickers!!!

What did you fix?

Did you have to add null pixels?

@Marc_MERLIN Well first I dumped ESP32 library and re-added since they had a new version, Then I updated the FastLED library. The last last key thing was added in #define FASTLED_SHOW_CORE 0
That took care of the flickering issue and now forcused on the Artnet/Wifi packet data.

@Jeremy_Spencer Did not have to add null pixels, but not done yet.

@Jeremy_Spencer null pixel become needed when using parallel output with my version of the library for case when more than 8 outputs are needed
